If you are getting lousy prints with smudges and lines like I show in this video, check out the toner’s drum. If your problems match the ones here then in all probability you should replace the toner. I did and now the printer produces laser sharp prints. If the printer has a separate toner drum then you will have to buy a new printer. In this case, the toner has the drum built-in which saved me from buying another printer needlessly when the 8 year 1740 is still running flawlessly.
